Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
High-arsenic refractory gold ores constitute the largest reserves but are the most difficult from which to extract gold. Gold leaching recoveries can often be as low as 50% ( Yang, 2005 ). These poor results can be attributed to the encapsulation of the fine gold particles—even at micron size—in pyrite or …

Arsenic ores are divided into several known types according to the commercial classification of ore deposits: arsenic (arsenopyrite and realgar-orpiment), gold-arsenic, complex-metal-arsenic, copper-arsenic, arsenic-cobalt, and arsenictin ores.
Modern methods of extraction allow economic leaching and electro-winning of copper from low-grade ores and extraction techniques are continuously being refined and developed to achieve the most efficient removal of copper from a wide variety of ores from sources around the globe.
This is a concern because Arsenic is actually very common in many gold ores. Selenium, mercury and other toxic elements are also found in many high sulfide gold and silver ores as well. To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don't want to melt them.
In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill. At the mill, the ore is ground into smaller particles with water, then ground again in a ball mill to further pulverize the ore.
By using 2M NaOH, 100° C, 40 psig O2, 10 pct solids, and 4 h, more than 90 pct of the arsenic was extracted from the high-grade ore. The gold and silver extractions were 90 and 76 pct, respectively, by cyanidation of the leach residue.
